Now it appears
that Iran's rapid progress toward a nuclear weapons capacity came thanks to substantial assistance from Pakistan
. Add that to the fact that we now know that North Korea's progress along the uranium-enrichment track (as opposed to plutonium) was similarly the product of key assistance from Pakistan. If we're looking for the unstable Islamist-leaning state which has nuclear weapons and is the chief proliferator of nuclear technology to other unstable rogue regimes, we've found it: Pakistan. The urgent question to be answered is whether such assistance is continuing. If it's ended, when did it end?
